Damaged Tevatron Equipment Replaced
Conning Tower Team

On Wednesday evening five technicians and one welder finished the replacement of 10 conning towers on spools in the Tevatron, allowing the accelerator to be cooled down again. Conning towers are used to lead strong electrical currents into the liquid-helium-filled interior of the superconducting Tevatron magnets.

Last Friday, a quench of two thirds of the Tevatron ring damaged one conning tower, causing a leak in the liquid-helium cooling system. To replace the tower, operators had to warm up one of the 24 cryogenic sections of the Tevatron to room temperature. The team replaced all of the section's conning towers

and completed the work half a day ahead of schedule.

"The original conning towers have weak joints that sometimes break in a quench," said TD's Dave Harding, who supervised the work. "Almost four years ago we began to replace conning towers with an improved design whenever a house had to be warmed up. We now have completed 14 of the 24 houses." The Accelerator Division will check the section for leaks, and Tevatron collider operations could resume by Tuesday.

Accelerator Division's Design/Drafting Group Decorates for the Season - Fermilab Style!

Design/Drafting group's seasonal decorations in MW9
The next time that you are in the Meson Area, stop by MW9 to see the Design/Drafting Group's seasonal decorations. Year after year the group decorates the tree with cryogenic artifacts and drafting instruments, such as triangles, french curves and circle templates. Without a doubt, these are decorations that can only be found at Fermilab.

Fermilab Singers' Annual Winter Concert Today

Fermilab Singers during a past concert
The Fermilab Singers will perform their annual winter concert today at noon in the auditorium. The 15 to 20-member chorale ensemble practices each Wednesday at lunch and performs at Fermilab a couple of times a year. "We have people in the singing group from all parts of the lab," said Anne Lucietto of FESS. "The alto section includes, among others: me (an American engineer), a French physicist, a Romanian student, and a Russian computer expert."

The group will perform a collection of mostly winter songs (some Christmas-themed, some Hanukkah-themed, some secular--witness "California Dreamin'.") In past concerts, the group covered gospel, Irish, Mozart, modern--usually in their original languages (French, Italian, German, Ladino, Hebrew, Dutch, Czech.) According to the director, Stephen Pordes, "We cover all styles we can get our hands on." Anne Heavey, the group's president, says that Pordes "has a real gift for finding the music."

The Fermilab Singers will also perform at their off-site debut this month. On Sunday, December 21, from 8:15 p.m to 8:45 p.m., they will perform at the Naper Settlement.

National Science Foundation facing budget let-down
By Geoff Brumfiel
[WASHINGTON] Science advocates in the United States are disappointed at a new spending bill that will give the National Science Foundation (NSF) far less cash than was recommended in a law passed just a year ago.
